How it works

A code point is parsed from U+ notation, hexadecimal, decimal, or a character, validated as a Unicode scalar value, and converted to UTF-8 bytes, UTF-16 code units, HTML references, CSS escapes, and JavaScript escapes. Supplementary code points use a braced JavaScript escape so they are not truncated.

  • Unicode scalar validation rejects surrogate code points and values above U+10FFFF.

Worked example

Lookup by Code Point
Look up Unicode character information by code point
Input
											U+0041
Output
												Character: A
Code Point: U+0041
Decimal: 65
Hex: 0x41
Octal: 0101
Binary: 1000001
Block: Uppercase Letter
UTF-8: 0x41 (1 byte)
UTF-16: 0x0041 (1 unit)
HTML Decimal: A
HTML Hex: A
CSS: \41
JavaScript: \u0041

When to use this

Encoding tests, font debugging, and markup escaping inspect code points.

Edge cases

  • U+1F600 uses \u{1F600} in JavaScript.
  • U+D800 is a surrogate and is rejected.
  • Values above U+10FFFF are outside Unicode.
